[issue12302] pysetup run test

[Michael Mulich]

New submission from Michael Mulich <michael.mulich at gmail.com>:

A package's metadata (dist-info) should be available to it while running the test command (pysetup run test)?

The use case:

I've written a test for a function that is supposed to find the default configuration or one provided in a users local area (or {userbase} as sysconfig puts it). As part of the test, I'm ensuring that the forcibly found default config is loaded correctly. The function that finds the configuration uses sysconfig paths (sysconfig.get_paths) which rely on the packaging database (PEP 376 API now in packaging.database).

To find the default config, or resource in packaging terms, I'm using the packaging.database.get_file_path, which requires the distribution metadata (dist-info) be available within the Python path, because it must lookup the RESOURCES file.

I've started work, in my local clone. We lack a unittest for this case. I'll be writing it some time within the next few days.

I'd like to know where this RESOURCES file came from? I don't recall, nor see mention of it in PEP 376. I would also have expected to find something in packaging.command.install_distinfo command related to this file. The install_distinfo command is lacking this logic. I'll add it after the first half of this case working.
